hello. My dad has been poorly for many years.  20 years ago he had rectal cancer and has lived with a stoma since then, and has lived a normal life until about 8 years ago when everything started failing him - he had kidney issues, and lots of urine infections, a very bad back. They said all his problems were due to over radiation 20 years ago. The past two years he's suffered from constant urine infections and can barely walk, has back pain, and is very fatigued.  Finally he was diagnosed after biopsy a few weeks ago with lung cancer, and has three small tumours. He lives in France and has no support like that which is available in the uk. The doctor told him he was very sick and told my stepmother he has a 'couple' of months to live. He has a PET scan scheduled for two weeks time - I presume to stage the cancer and see if it has spread?

My stepmother is in denial and insists he is in no more pain than usual (!). She also hasn't told him of his time left. 

Pa has started to withdraw and for the first time ever didn't kiss me hello or even say hello when I visited him last month. He shuns any kind of physical contact. His usually boisterous dog is as docile and calm as anything (I think dogs know, somehow??). 

I have experience of two friends with lung cancer who two weeks before their death seemed 'fine" and then all of a sudden they declined and died in two days. Is this normal with lung cancer? Are there signs before hand or is it usually sudden? I want to be able to get to see him in time but it's difficult as my stepmum seems to think every day is the same as the last. 

He is not having any treatment as he is too weak to support even surgery for a fistula- the doctor suggested palliative care. He is not getting any other assistance currently and seems to have been left to his own devices.

Does anyone have experience of the end days of lung cancer?

thanks very much.
